7 Service Parameter to Data Item Mapping
7.1 Table 2 shows the mapping between message parameters defined by CIDRW and data items defined by SECS-
II. For parameters specified in the definitions of a CIDRW service, either the parameters themselves, or individual
elements of complex parameters, map to a specific data item.

Identifies either an individual head (“01”-
“31”) or the CIDRW subsystem itself (“00").
PM Information STATUS 20 “NE” = Normal execution, “MR” =
Maintenance required
Result Status SSACK 20 “NO” = Normal operation;

NOTE 1: There are also data items used in SECS-II messages that do not map to specific services parameters. Services with the same set of
parameters are mapped to the same SECS-II message by adding an additional data item to differentiate between the services. Table 3 contains the
SECS-II data items that have not a corresponding CIDRW service parameter:
